The quiet side of the country
Eastern Mongolia is the least visited of the main regions. It generally covers the provinces of Dornod and Sukhbaatar, and often the eastern parts of Khentii. The terrain is a broad, gently rolling plain, with few mountains and long horizons. Most travelers go west, south or to the north, so the east has a reputation for being empty. That is partly true, but the emptiness is the point. This is one of the largest areas of continuous grassland left in the temperate world, and very little of it is fenced or built up.
Landscape
The eastern steppe is flatter and more open than the central valleys. Grass is the main vegetation, with low hills, scattered rock outcrops and occasional extinct volcanic cones in some areas. The climate is continental, with warm summers, cold winters and rainfall that is limited but generally better than in the Gobi. A good rainy summer can turn the plain green and full of wildflowers, while drought years can leave it brown.
Several rivers cross or border the region, and some drain toward the Amur basin to the east rather than toward the Arctic or inland basins. Marshes and lakes dot the lowlands, and a large lake area lies on the border with China. This water makes the east a significant place for birds, and it connects to wider steppe landscapes across the border. The scale is difficult to appreciate from a photograph: the main experience is distance and sky.
Wildlife
The east is best known for its large herds of Mongolian gazelles, which move across the plains in search of better grazing. These movements can involve very large numbers and are among the more striking sights in Mongolia, although where and when the animals gather varies from year to year and cannot be predicted. The gazelle migration has its own article.
Other wildlife includes birds of prey, cranes and other wetland birds, particularly in spring and fall when migrants pass through. Marmots and other small mammals are common. Some of the cranes that breed in the area are rare globally. Wolves live here, as elsewhere in Mongolia.
Large protected grassland areas have been set aside in the east, and the eastern steppe reserves are described in their own article. Park rules and fees apply, and travelers should check them before arrival.
History on the plains
The east has its own place in Mongolian history. Several traditions about the early life of the Mongol leader Genghis Khan point to the northeast, in the Khentii area, though the exact locations of specific events are debated by scholars and should be taken with caution. The Khentii Mountains are covered in a separate article.
In the twentieth century, the border country was the scene of a significant military clash in 1939, fought on the plains near the Khalkhin Gol river between Soviet and Mongolian forces on one side and Japanese forces on the other. A museum and memorials mark the history in the area. The conflict is a reminder that these quiet grasslands have long been strategic ground, and it forms part of the broader story of Mongolia in the twentieth century.
Border country
The east borders both China and Russia. Some border areas are restricted, and permits may be needed to enter them. These rules change and can be strict, so check with current official sources and local contacts rather than relying on older information. Do not approach border markers or fences without checking. Entry requirements for the country as a whole are a separate matter.
People and herding
Herding families live across the east, and sheep, goats, cattle and horses are the main animals. The region is home to Mongolian groups such as the Khalkha, with Buryat communities in the northeast and others in the border areas, each with its own customs. Compared with central Mongolia, there are fewer visitors in the east, so hospitality tends to feel less commercial and more personal. Visitors should still follow ordinary customs and ask before photographing people.
Getting there and practicalities
Roads are long and often unpaved. Flights to provincial centers such as Choibalsan exist at times, but schedules vary, and many visitors travel overland with a driver. Services between towns are sparse, with limited fuel, food and repair options, so planning is important. Weather can change quickly, and wet-weather tracks can become difficult.
Summer is the usual season for visits, when pastures are at their best and wildlife is most active. Winter is very cold and windy, and visiting then needs good preparation.
Why visit
The east suits travelers who prefer open space and quiet to famous landmarks. It does not offer dramatic peaks or sand dunes, and visitors should not expect them. It does offer a rare look at a vast, relatively undisturbed grassland, rich bird life, and a sense of the Mongolian steppe as it appears to those who live on it. It can also be paired with a visit to the Khentii area on a longer trip, though the distances involved are considerable.
